Although this small-screen player began studying acting in the early '80s, he struggled for almost a decade before shooting to stardom in 1990 as a cranky New Yorker practicing medicine in Alaska on the quirky dramedy Northern Exposure. Previously, Morrow appeared primarily on stage and cofounded the prestigious off-Broadway theater company Naked Angels. Despite his success on Northern Exposure, he left the show in its fifth season to pursue big-screen roles, with little success. He returned to series television in 2002 as an ex-con on the short-lived Street Time. The role helped him overcome his nebbishy typecasting, and in 2005 he signed on to Numbers as an FBI agent. Morrow also has a burgeoning career behind the camera as a director and helmed the independent feature Maze, which he also wrote, co-produced and starred in.
